IMPROVEMENT IN ELEVATORS.

Specification forming part of Letters Patent No. 142,555, datedSeptember 9, 1873; application filed June 3, 1873. 1

To all whom it may concern:

Be it known that I, ERASTUS BOYDEN, of Lowell, in the county ofMiddlesex and Commonwealth of Massachusetts, have invented a new anduseful Improvement in Elevators for Cotton-Laps, to be used in mills, ofwhich the following is a specification:

My improvement consists, first, in provid ing an elevator forcotton-laps and other like articles with an automatic starting andstopping device, so that the same shall elevate the laps from the tableof the machine successively out of the way, and stop automatically atthe proper point to receive another lap, the object of this part of myinvention being to save the expense and trouble of a person to watch andstop and start the elevator properly to receive and deliver the laps;second, in providing the elevator with a table and trough, connectedtherewith as hereinafter described, for the purpose of receiving thelaps thereon and removing therefrom the metal lap-roll on which the lapis formed in the lapper, and inserting in place of the laproll thewooden rod or bar which supports the lap while being transported on theelevator; third, in providin g the elevator with a set of double orreverse hooks or carriers, so that they may transport the rods or barswhich support the laps after they are removed from the latter down onthe side of the elevator opposite to the ascending laps, to be againused in transporting laps up the elevator.

Figure 1 is a front view of my improvement as attached to an elevator.Fig. 2 is a side view of the same.

A is an elevator, formed of two bands, 01 d, of leather or othersuitable material, passing around the wheels on a at some distance fromeach other upon their axis. The wheels at a at the top of the elevatorare upon the same axis 1), and those at the bottomare also upon the sameaxis 0, whereby a simultaneous and uniform ascending and descendingmotion is insured to the bands d cl. The elevator A passes up from thefloor e of the lapper-room through the floor f of the room above, wherethe laps are to be used. C is a table placed at a suflicient distanceabove the floor 0 to conveniently receive the laps as they arebroughtfrom the lapper. At the side of the elevator is placed a shaftcarrying a tight and loose pulley, t i, over which runs a beltconnecting them with suitable motive power for driving the machine. Onthe same shaft with the tight and loose pulleyi t" is a second pulley,which is connected by a belt with the pulley j, which, in turn,communicates motion, by intermediate pinions, to the gear-wheel t',which is attached to and drives the shaft on which are the upper wheelsat a, thus operating the elevator. Connected with the belt which drivesthe pulleys i i isa belt-shipper, c, for shifting the belt from thetight pulleyi to the loose pulley i, or vice versa, this belt-shipperbeing pivoted on the arm 0, and having attached to its end, opposite thebelt, the rod 0', extending down below a trough, 0, near the table 0.The trough c is placed at the side of the table G, and a little aboveit, extending in a line with the rods n n, which support the laps inhooks upon the elevator. At the lower end of the rod 0' is pivoted therod 6, which extends under the trough e, and has its outer end turnedupward at a right angle, and projecting in a longitudinal slot throughthe bottom of the trough upward into it, so as to be capable of beingmoved in the trough along the direction of its length. On the bands ddare firmly secured hooks o 0, adapted to receive and carry the ends ofthe rods to a at suitable distances apart, the hooks 0 0 on one bandbeing directly opposite those on the other. The rod 0' being suspendedupon the belt-shipper at its upper end, its weight is sufficient to keepthe driving-belt running upon the fast pulley 43 and the elevator inoperation, while at 'the same time it can swing away from the elevatorwhen the rod c is moved along in the slot in the trough c. On the rod 0'is a short arm, 00, just above the trough, projecting at right angles,so as to engage with the hooks 0 on the adjacent band at as they risewith the band.

When the arm 00 and rod 0' are lifted and supported by one of the hooks0, the drivingbelt is thereby shipped onto the loose'pulley t, and theelevator stops. On the lower side of the trough e the rod 0 is 'heldtoward the elevator by a spring, which keeps it and the arm 00 in aposition to engage with the hooks 0 as they rise.

In order to operate the elevator, one of the hooks 0 is set so as tolift the arm as and rod 0' and shift the driving-belt onto the loosepulley t". The lap is placed by a workman on the table G, having a heavyiron lap-roll, on which it is formed, passing longitudinally through itscenter, the ends of which are made to rest very nearly against the facesof the bands d d at each end of the lap, the bands being far enoughapart to admit the length of the lap between them. The workman thentakes one of the rods a, which is long enough for its ends to rest inthe opposite hooks o 0, and, placing the end of the rod against the endof the lap-roll in the lap, shoves the latter out (the rod replacing it)in the direction of and into the trough 6. Just as the lap-roll leavesthe lap its outer end comes in contact with the projecting part of therod 6 in the trough, and moves the rod along the trough outward, drawingthe rod 0' away from the elevator and the arm .00 out of the hook 0, andallowing the weight of the rod 0' depending from the belt-shipper toship the driving-belt onto the tight pulley i, and set the elevator inmotion. The workman adjusts the ends of the rod a into the hooks o 0 ateach end of the lap, and the elevator carries the lap upward. Theworkman then removes the lap-roll from the trough e, and the spiralspring throws the rod 0, rod 0', and arm as into place, ready to engagewith the next hook 0 as it rises. When the next hook 0 reaches the arm00 it lifts the arm, ships the driving-belt onto the loose pulley, andthe elevator stops in position to receive the next lap.

The hooks 0 0 on the bands d cl are made double or reverse, so as tocarry down the rods n n from the upper floor of the mill as fast as theyare removed from the laps. On the descending side of the elevator anarm, 2, is placed, so as to discharge the rods it upon the table as theyare brought down. A brake or pawl, r, is applied to the pinion which isdriven by the pulley j, so as to prevent the pinion from moving in thedirection opposite to that given it when driving the elevator. Thisbrake or pawl thus keeps the elevator and its loadstationary when thedriving-belt is running on the loose pulley i.

What I claim as new and my invention is- 1. In combination with theelevator A, the automatic stopping device, consisting of the arm a; andbelt-shipper 0, connected by the rod 0', substantially as described.

2. In combination with the elevator A, the automatic starting device,consisting of the trough 0, rod 6, rod 0', provided with its arm 00 andbelt-shipper c, substantially as described.

3. In combination with the elevator A, the tableO for receiving the lapwhile the laproll is being removed therefrom, substantially asdescribed.

4:- The trough e, in combination with the table 0, placed at a properheight to receive the lap-roll from the lap upon the table,substantially as described.

5. The double or reverse hooks 0 0, attached to the elevator A, so as totransport the rods n 011 the opposite side from the laps, substantiallyas described.
